Little Lava Lake is a great spot for the week. Chironomids and Blood Worms fished near the bottom in 10 to 16′ either under the indicator or with a Emerger tip or Ghost Tip sink tip line and a S-L-O-W retrieve. 
Chubbies and Beetles along the edges and weed beds. Still some afternoon callibaetis too. 
If you haven’t added the Red Holographic Jig to the lake box, and you’re headed to Little Lava (or Homer) come grab some or tie your own on a #14-18 jig hook, a 2.3 gold bead, CDL tail, stripped peacock herl body and about 3 turns of red holographic tinsel for the thorax. It’s killer and is becoming one of my top “go to” flies for all the lakes.
